    Water consumption behaviour and the use of technology among households in Durban, South Africa
    (IWA Publishing, 2023-04-21) Ngcobo, Mbuso; Murwirapachena, Genius; Reddy, Maliga
    Freshwater resources remain under constant pressure due to population growth, economic development, and changing weather patterns. Water supply utilities generally struggle to keep up with the growing demand for freshwater resources and consequently adopt demand management policies to address supply challenges. As water consumers, households can play a major role in water conservation. This paper examines the impact of biographic characteristics on water consumption behaviour and the adoption of water-efficient technologies in the city of Durban, South Africa. Probit regression models are estimated using survey data collected from 300 household heads sampled across the city. Among other results, the study finds income as the most consistent determinant of water consumption behaviours and the adoption of water-efficient technologies. Furthermore, the level of education was also found to be a consistent determinant of the adoption and installation of water-efficient technologies. These results are significant and serve to guide water utilities when implementing demand management water policies.

    The water crisis in Durban : an analysis of the role of households in water conservation
    (2021-11) Ngcobo, Mbuso; Murwirapachena, Genius; Reddy, Maliga
    The continued water crisis in South Africa is causing many municipalities to exhibit performance problems in water service delivery. While South Africa is a water-scarce country, factors like population growth, climate change, urbanisation, and economic development contribute to water shortages. This implies that new and innovative ways of managing freshwater resources should be adopted. This study aims to examine the role of households in water conservation in the city of Durban. The study fulfils four main objectives to achieve this aim. The first objective is to establish the daily water consumption behavioural practices of households. Secondly, the study seeks to establish the households’ willingness to adopt water-saving technologies. Thirdly, it seeks to identify the factors preventing households from practising water-saving behaviours. Furthermore, the study finally seeks to recommend some possible solutions that the eThekwini Municipality could adopt to promote households’ water conservation. The study uses a mixed methods approach where quantitative and qualitative data are separately collected, analysed, and discussed. Quantitative data is collected through a survey conducted on 300 household heads residing across different spatial residential areas. On the other hand, qualitative data is collected from seven (7) employees in the Water and Sanitation Unit of the eThekwini Metropolitan Municipality. The thematic approach is then used to analyse the qualitative data, while descriptive statistics and probit regression models analyse the quantitative data. Four key findings are reported in the study. First, the study found that households in the city of Durban generally practice water-efficient behaviours in their daily water consumption activities. Secondly, the type of access to potable water services was the primary determinant for practising water-efficient behaviours. Third, more residents in the suburbs and townships have water-efficient technologies installed, while none of the respondents from the informal settlements has such technologies installed. Lastly, some biographical characteristics emerged as crucial determinants of water consumption behaviour and the adoption of water-efficient technologies. Key recommendations are given based on these findings.
